Operation principle of the present invention is described as follows:
Take this device is below example explanation operation principle of the present invention (as Fig. 2) as three automatic drilling unit head circulation automatic drillings in machining.
Before start, workpiece and three unit heads are installed and are adjusted to the right place, and manual rotation screw mandrel 202 just can accomplish that slide unit 103 is positioned at and initial stop screw 109 contact conditions, now, retreat switch collision block 211 and pressing backward travel switch 210,206 one-tenth compression state of rear extractor.207, the spring that advances is in relaxed state, forms the state that slide unit 103 tightly heads on initial stop screw 109.Be subject to the realizing middle limiting screw 112 on the realizing middle limiting piece 111 of extraneous driving mechanisms control to be in the position facing to slide unit 103.
During start, 301 startings of unit head of automatic drilling, process workpiece 300, while finishing return, touch the travel switch that stops on a unit head 301, interlock external circuit controller, and external circuit controller is being controlled motor 201 and is being driven screw mandrel 202 rotations.Affected by the elastic force of extractor 206 after high compression, at the beginning, slide unit 103 is motionless, motor 201 in succession screw mandrel 202, motor fixing plate 203, guide pillar 205, guide pillar plate 204, retreat switch collision block 211 and frictional force that the switch collision block 209 that advances overcomes self gravitation and front bearing 105 and guide pillar 205, screw mandrel 202 to retreating away from slide unit 103 directions, retreat before this after switch collision block 211 departs from backward travel switches 210 and continue to retreat.Until after stop retreating during the balance of extractor 206 and the operation friction Lixing Cheng Xin of advance spring 207 and slide unit 103, change slide unit 103 into and advance to realizing middle limiting piece 111 directions along guide rail 102.When the slide unit 103 of the nut 104 of ining succession in motion is encountered realizing middle limiting screw 112, be obstructed and halt, in succession screw mandrel 202 of motor 201 continues rotation, reaction force cause motor 201 in succession screw mandrel 202, motor fixing plate 203, guide pillar 205, guide pillar plate 204, retreat switch collision block 211 and frictional force that the switch collision block 209 that advances overcomes self gravitation and front bearing 105 and guide pillar 205, screw mandrel 202 retreats to motor 201 directions.Oppress gradually the spring 207 that advances, simultaneously, extractor 206 loosens gradually, when the switch collision block 209 that advances is encountered forward stroke switch 208, motor 201 power-off that external circuit controller is being controlled shut down, the rotatory inertia producing while stopping, allowing advances after spring 207 continues to compress a segment distance stops, on the realizing middle limiting screw 112 that slide unit 103 is rested on tightly head on realizing middle limiting piece 111, simultaneously, No. two unit head 302 startings are being controlled in 208 interlocks of forward stroke switch, and workpiece 300 is processed.While finishing return, touch the travel switch that stops on No. two unit heads 302, interlock external circuit controller makes motor 201 reversions, the time meter electrical equipment of controlling motor 201 reversions synchronously starts timing, when slide unit 103 leaves after 112 1 sections of distances of setting arbitrarily of realizing middle limiting screw, then, the extraneous driving mechanism that interlock external circuit controller is controlled runs to realizing middle limiting piece 111 and realizing middle limiting screw 112 position that disengaging interferes slide unit 103 to move on guide rail 102 to time meter electrical equipment.Meanwhile, the external circuit controller that also links is being controlled motor 201 and is again being reversed, and drives slide unit 103 terminad limited blocks 108 to advance.When slide unit 103 is encountered end stop screw 110, be obstructed and halt, the same with the principle of encountering realizing middle limiting screw 112, when the switch collision block 209 that advances is encountered forward stroke switch 208, motor 201 power-off shut down, No. three unit head 303 startings are being controlled in interlock, workpiece 300 is processed, while finishing return, touch the travel switch that stops on No. three unit heads 303, interlock external circuit controller, make motor 201 reversions, drive slide unit 103 to advance to initial limited block 107 directions, when slide unit 103 is encountered initial stop screw 109, be obstructed and halt, the same with the principle of encountering end stop screw 110.Difference is that traffic direction is contrary, and in the time of rear extractor 206 compression, the spring 207 that advances loosens gradually.When retreating switch collision block 211 and encounter backward travel switch 210, the motor 201 that external circuit controller is controlled stops, and interlock is simultaneously being controlled realizing middle limiting piece 111 and got back to initial position ，Ji Gai mechanism and get back to original state.A work period finishes, and changes after workpiece 300, and restart switch, can carry out the new round work period.
